When the locking other causes.

.Jar is in this position the end or central proieetions will rest firmly on the angle plate or rail, and against the vertical port-ion of the augle-plate or fish-plate.

An important feature of my invention is the resilient force of the bar to hold and keep the nuts in place when loosened or displaced by the jarring caused by passing trains or from The bar being cut out of sheet metal and then bent into shape gives it a resilient force to resist the slightest movement ot'the nutand force it back intoplaee and hold itthere. This result cannot be obtained in locking-bars made solid of cast, malleablc,or wrought iron, as such bars possess very little if any rcsill iency. This lockingbar is light and simple in its construction, dispensing with the use of a large quantity of metal, and thus avoiding the casting or construction of a cumbersome and heavy bar.

A further advantage of this bar is that it conforms to the contour and arrangement of any angle-plate or fishplate, or the variation caused by the use ofdifle "ent sizes of nuts, or by adjustment of same thus avoiding the ne- 1 eessity of constructing it to lit the plate to which it is desired to apply it.

It is obvious that any form of not can be 4 readily used in construction with this bar other than thoseshown and described without changing the form of the barand necessitating a departure from the nature and principle of my invention.

I am aware that looking bars have been used in connection with angleaud fish-plates, which are constructed to conform to the shape of the plate used, and such I do not claim;

\Vhat I do claim as new, and desire to secure by Letters Patent, is-

As an article of manufacture, a nut-locking bar made of sheet metal and having two end projections in the lower portions thereof con nected by a recessed web, a top web bent at an angle to the lower web and having a series of projections forming side washers for the nuts, formed by recesses in the upper web, and means for securing the bar when in position, substantially as described.

In testimony whereolI afiix my signature in presence of two witnesses.
